300W TFX PSU for HP Slimline s5304y s5305z

This new myVolts TFX power supply delivers 300W of continuous power for HP Pavilion Slimline s5304y and s5305z CTO desktops. It uses an AT form factor with an 80mm double ball bearing fan for cooling. The unit accepts 100 to 240V input and weighs 3 lb. It serves as a direct replacement for failed or underpowered original units in these specific slimline chassis.

Who this suits and who should look elsewhere

This unit suits owners of the listed HP Slimline models needing a 300W TFX replacement with standard 20+4 pin motherboard, 4-pin CPU, three Molex, floppy and three SATA connectors. It also supports upgrades from 200, 250 or 350W configurations. Builders requiring higher wattage than 300W, a different form factor such as ATX or SFX, or modular cabling should look at other options.

Deciding spec: 300W TFX output for Slimline s5304y

The single specification that decides fit is the 300W TFX form factor matched to the HP Pavilion Slimline s5304y and s5305z CTO. Only this physical size and connector layout will install correctly in those chassis. Verify your model number exactly before ordering; other Slimline or SFF models may use different PSU dimensions or pinouts.
