Rosewill PSUs are always great


This is a great PSU for the price point. If you're looking for something that puts out enough power for most low to mid-end builds, but doesn't cost a ton of money, this is a great PSU to go with. I've always used Rosewill PSUs, and have never had any...

Great quality ; Price point ; Puts out the power that it's supposed to ; Connectors for most common drives/cards

500W Stallion Workhorse


For those that don't know, Rosewill is Newegg's house brand which have been known to be manufactured by ATNG (Extreme & Performance Series), ABS (Libetas), Solytech (Stallion), and Deer (Value).

Normally I don't write reviews but I bought this power supply in Jan of 2010 and it has been providing juice to a very modest AMD Athlon II X2 240 Regor and an XFX GeForce GTS 250 for almost 4 years virtually 24/7 with no problems at all. If you are...

Stopped working after 3 months. Came home and tried to boot up my PC, nothing. Tried it in another PC and still no dice

Decent entry level power supply


Well it's a power supply, the blue LED is nice and it came with a case for a built for my friend. Good entry level PSU can with came in a bundle. The cables and headers are nicely labeled

The PSU has VERY short cables my friend had tough time even reaching the 24 pin connector on to MOBO in a mid tower case. The PSU is also quite loud

Second one arrived dead


This is the only item I've ever had issues with from Newegg. Avoid Rosewill.


Just received replacement for first PSU that arrived DOA. Replacement has been fully tested and is DOA as well. I've lost three weeks of work since ordering first unit, and now I'm going somewhere else b/c I can't afford to wait for another RMA...

Consumer review by:



Now I'm stuck paying to ship it back and even more wait.

Wires nicely bundled

Unit arrived DOA. First problem I've ever had with a product from Newegg
