i'm planning to buy Radeon hd4850. my PSU is the AcBel 510w currently powering; E8200(at stock speed), 1dvdrw PATA, 1 SATA hdd, 1 PATA hdd, 2 X 1gb DDR2 (800), 1 PCI 56k modem, 3 120mm fans . i would just like to ask if my PSU can handle if i install a Radeon hd4850. i've already gone to eXtreme Power Supply Calculator, and the estimated wattage was 285w, but i just wanna make sure to avoid hassle after buying the vid card. any info is greatly appreciated, most especially if you're using the same PSU. thank you. btw, my mobo is a matx (Gigabyte GAG31M-S2L).
