The stuff Dale wants tro buy wouldn't even reach 250ł AT FULL LOAD. |

Even my rig - hotter, doesn't reach 300W when I artificially torture the |
| 18 |
system. Normal 'max' load is in 200W range. An normal desktop? Under 100. |

You don't want to get to far below 20% PSU load or efficiency is shot. |

So an 800W PSU is stupid in every regard. 650 is way to big. 450 is good |
| 23 |
enough. 400W might even be good enough. |

Aren't those rebranded Seasonics? |

which are all powered by PSU sellers... |

my current ASUS board is a piece of shit. Two repairs because the board loves |
| 42 |
to fry the bios chip. When the box is on but not used for a while, it might |
| 43 |
lock up completely. So completely I had to remove the battery and set the bios |
| 44 |
jumper to get it back working. Asus has become worse than their daughter |
| 45 |
Asrock. |
| 46 |
Nothing bad to say about Gigabyte. I am still waiting for a reply from their |
| 47 |
support. Send the mail 12 years ago ;) |
