TFX upgrade for HP Slimline

The myVolts TFX power supply replaces the original unit in HP s5703w and S5716F desktops. It delivers 420 W output, upgrading systems that shipped with 200 W to 400 W units. The AT-type design fits slimline and small-form-factor chassis. It is built for owners of those specific HP models who need more headroom for added components.

80 mm double ball-bearing fan cooling

An 80 mm fan with double ball bearings handles thermal management during normal operation. The unit accepts 100/240 V input, allowing worldwide use without a voltage switch. Power draw scales with the connected load up to the 420 W rating. No noise-level or efficiency figures are provided by the supplier.

20+4 pin, 4-pin CPU, three SATA, three Molex, floppy

The cable set includes a 20+4 pin motherboard connector, a 4-pin CPU connector, three SATA power plugs, three Molex plugs and a floppy connector. This mix supports legacy and current drives in the target HP systems. No modular cables, software utilities or extra mounting hardware are mentioned in the specifications.

Perguntas sobre este artigo

How do I install this TFX power supply in my HP s5703w, and which connector step is often missed?

Fit the unit into the slimline chassis, secure it with screws, then attach the 20+4 pin motherboard plug, the 4-pin CPU plug, three SATA leads, three Molex leads and the floppy connector; the 4-pin CPU plug is the one most often forgotten.

What maintenance will this 420 W TFX unit need over time?

The 80 mm double ball-bearing fan is the only moving part; clean dust from its intake and exhaust vents every few months to keep airflow steady.

What limit appears first when this supply runs at high load for long periods?

The 420 W total output ceiling is reached before any single rail limit, so sustained draws above that wattage will trigger protection shutdown.
