Have used several since 2008


It's always important to have reliable PSU. If a PSU dies, sometimes it can take your entire build with it and if can destroy components attached to it. This unit is my go-to for mid-level builds (business/office/light-mid gaming). This card wont be...

I've used this unit in multiple builds starting in 2008. I have never had one fail. I just recently sold the original unit I bought back in 2008 which was still 100% functional

I would prefer a modular PSU for better cable management, but that's a minor gripe

I like it


This was in a build for my wife. MB: Asus P8B75-V (LGA 1155) CPU: Intel Core i7-3770 (No OC) 3.4ghz 3.9 turbo Mem: 8Gb (4x2Gb) Aeneon XMP 1600 9-9-9-28 GPU: Intergrated Intel HD4000 Graphics HD1: Verbatim SATA II 256Gb SSD for OS HD2: Verbatim SATA II...

It works perfectly for the system I built for my wife ; Great value

None i can think of. The limit of 4 SATA conections was easily fixed with the addition of a couple of adapters

cheap but has it's +'s and -'s


over all this is a nice psu for micro systems only if you are using a mid size tower you can make it work , if you have a full size or + size tower avoid at all costs unless your case has the PSU at the top and well thats just not pro ;-)

I used this in a system build i did for a friend and over all it's nice. I wanted something black with no LED's because the theme was black and green so this worked nicely. the fan is quite and the cables are nice and sleaved. It has 2 lines of sata...

Main problem is cable Length. I find they are short to do proper cable managment in a mid size tower and on a full size tower this psu would not even be a option!. If you face the fan down sucking air in (not recomended) you barely have enough room to...

Rosewill RD450-2-SB


bought back in 2010 and still running strong. More than enough to run my system ; 1st generation i 5 ; 8 gigs ddr3 ram ; dvd write ; memorycard reader ; sata hardrive ; case with 3 fans


Consumer review by:

Works just as it should


I got this because i updated my GPU old power supply could not handle it it work exactly as it should no extra noise just as quiet as the stock one

None that i can think of it does exactly what i wanted it to

Bad Plastic parts


Would not buy another one.

It still runs after a year which is good thing with chinese stuff. Cheap

The plastic connectors break so easily. Be super carefull when you use the sata connectors. The plastic is very brittle

Great PSU So Far!


If you need more than 1 6-pin video hard adaptor this is not the power suppy for you.

Power supply is great for what I need it for! I only have one video hard, 3 internal hard drives and my motherboard so there are plenty of power connectors for that. It's not too loud and is powerful enough to run all my HD's, CD-ROM drive, 8800 GTS...

None so far
