AI Verdict
This is a bare-bones, non-modular 700W power supply that trades high-end efficiency and aesthetics for raw wattage, making it strictly for entry-level builds and office PC revivals.
If you are building an entry-level PC or upgrading an old Dell, this 700W unit provides massive headroom. Its older group-regulated internals and basic 80+ White efficiency make it a risky pairing for expensive, modern hardware.
If you are powering an RTX 4070 or higher, step up to an 80+ Gold, fully modular unit with a DC-to-DC topology.

Pros
- Delivers 700W of continuous power, easily handling mid-range cards like the RTX 3060.
- The 120mm cooling fan stays surprisingly quiet even when the system is under moderate gaming loads.
- Backed by a 5-year warranty, which is rare for an 80+ White certified entry-level unit.
- Compact 140mm depth fits easily into older pre-built cases like Dell Optiplexes.
Cons
- Non-modular design means you have to stuff unused SATA and Molex cables into your case basement.
- 80+ White certification guarantees only 80% efficiency, pulling more electricity from the wall than Bronze or Gold units.
- Uses an older group-regulated design that struggles with the aggressive power spikes of modern high-end GPUs.
- Cables lack premium black sleeving, exposing red and yellow wires in windowed cases.
Dimension Scores
80+ White is the bare minimum standard today, and the group-regulated design is outdated.
The 120mm fan stays remarkably quiet for an entry-level unit, rarely spinning up to annoying levels.
It survives years of use in basic rigs and carries a 5-year warranty, but uses cheaper internal capacitors.
It is completely non-modular with stiff, unsleeved colored wires that are a nightmare to hide.
Best For
- Reviving older office PCs with an entry-level dedicated graphics card.
- Entry-level 1080p gaming builds using 65W CPUs and mid-tier GPUs.
- Flipping used PCs where keeping the total component tier strictly capped is critical.
Not Recommended For
- Modern high-end gaming rigs with power-hungry GPUs like the RTX 4080 or RX 7900 XTX.
- Mini-ITX or compact cases where hiding a massive bundle of unused cables is impossible.
Watch Out For
- The non-modular cables are bulky and stiff — you will need a case with a dedicated PSU shroud to hide the mess.
- It ranks in Tier E/F on enthusiast PSU tier lists due to its older internal topology, meaning it shouldn't be trusted with flagship components.
- The 80+ White rating means it generates more heat and wastes more electricity than modern 80+ Gold units, which could cost you more on your power bill over 5 years.

What Buyers Say
The divide between PSU enthusiasts and actual buyers couldn't be wider here. On Reddit tier lists, this unit is heavily criticized for its outdated group-regulated design and basic 80+ White efficiency. In Amazon and Best Buy reviews, thousands of buyers praise it as a reliable workhorse that easily powers entry-level builds like an i5 paired with an RTX 3060. The biggest recurring headache is the non-modular cable mess, with users forced to shove a massive bundle of unused Molex and SATA cables into their case basement. Despite the ugly 'ketchup and mustard' cables, it consistently delivers stable power without the fan sounding like a jet engine.
“It powers my 3060 without blowing up and the fan is quiet, but trying to hide all these ugly mustard cables in my case was a total nightmare.”
Common Praise
- The 120mm fan is virtually silent even when pushing the system during 1080p gaming.
- Provides 700W of headroom for entry-level builds, making it a staple for PC flips.
- Fits perfectly into older pre-built cases like Dell Optiplexes to support dedicated GPU upgrades.
- Runs stable for years without random shutdowns on mid-range hardware.
Common Complaints
- The non-modular design leaves a massive nest of unused cables that are incredibly hard to hide.
- The cables expose ugly red and yellow wires right at the connectors, ruining the look of windowed cases.
- Lacks the extra CPU and PCIe cables required for modern, high-end motherboards and graphics cards.
- Draws noticeably more power from the wall at idle compared to 80+ Gold units.
Ownership Tips
- The fan curve is very conservative, meaning it stays quiet but the unit itself can get slightly warm to the touch under heavy load.
- The SATA power cables are spaced a bit awkwardly, making it tough to connect multiple drives mounted far apart.
- Dust buildup is minimal after months of use, but the fan grille cannot be easily removed for deep cleaning.
Frequently Asked Questions
Does this come with the cables I need for my graphics card?
Yes, it includes two 6+2-pin PCIe connectors. This is enough to power most mid-range graphics cards, but not enough for high-end cards requiring three 8-pin cables.
Is this power supply modular?
No, all cables are permanently attached to the unit. You will need to find a place inside your case to hide the cables you don't use.
Will this fit in a micro-ATX case?
It uses the standard ATX form factor with a 140mm depth, so it fits most micro-ATX cases. Just be prepared for a tight squeeze when managing the non-removable cables.
What does 80+ White mean?
It is the lowest tier of the 80 Plus efficiency rating system. It guarantees the unit operates at 80% efficiency under typical loads, meaning 20% of the power drawn from the wall is lost as heat.
Is this PSU loud?
The 120mm fan operates at a maximum of 1800 RPM and users consistently report it stays quiet during normal desktop use and moderate gaming.
Buying Guide
When buying a power supply, wattage isn't the only thing that matters. A 700W entry-level unit like this is built with older internal designs that are perfectly fine for a basic graphics card, but risky for a high-end graphics card that demands rapid power spikes. You are also sacrificing cable management — non-modular means every single cable is permanently attached, so you need a case with room to hide the leftovers. If you just want reliable power for a basic gaming rig, this works, but don't put it in a flagship machine.
80 PLUS White Certified
Think of this like gas mileage for your PC. 'White' is the lowest rating, meaning it pulls more electricity from your wall to deliver the same amount of power to your parts compared to a Gold or Platinum unit.
Non-Modular
Like a multi-tool where you can't fold the blades away. Every cable you might ever need is permanently attached, so you have to find a place to stuff the ones you don't use.
Active PFC
This acts like a surge protector inside the power supply itself, smoothing out the electricity coming from your wall so your sensitive PC parts get a steady, clean stream of power.
Alternatives
If you are powering expensive modern components or building in a case with glass panels, search for an '80+ Gold Fully Modular ATX power supply' to get better efficiency, safer power delivery, and removable black cables.
