Lol yeah. I would actually recommend the 450W, but the 400W would do just fine. Read this review on the 450W.
"I bought this PSU almost 2 months ago for my PC build consisting of an intel pentium D 830, 4 sticks of DDR2, 7800GTX video card, 1 SATA HD, 2 CD/DVD drives, floppy and tv tuner. So far no problems. Great product! Thanks Newegg!"
